Introduction

Based on deforestation rates, climate change predictions, and the extent of current land-use change, Southeast Asia is a region of high conservation priority (Sodhi et al. 2010a, Brooks et al. 2006). However, ecological research efforts and suitable protection of species naturally depend on the knowledge of species occurrences in a particular area. This information in readily accessible form is lack-ing for several taxonomic groups and regions in Southeast Asia (Sodhi and Brook 2006). In order to facilitate argu-ments to policy makers for the protection and preservation of invaluable conservation areas and informed ecotourism (i.e., knowledgeable local guides), such accessible data is of crucial importance.

The island of Sulawesi (Indonesia) is a hotspot of en-demism even on a global scale (Whitten et al. 2002), but knowledge about herpetological diversity and identifi-cation literature are both very limited (but see de Lang and Vogel 2005 for snakes). This is a worrying tendency

as these two taxonomic groups contain many of the most threatened vertebrates on the planet (IUCN 2009, http://www.iucnredlist.org) and the ecological impacts of land-use change urgently need to be better understood (Sodhi et al. 2010b). Based on three years of collecting survey data and the available literature, we here provide the first her-petological species list with IUCN threat status and infor-mation on abundance, habitat use, and maximum eleva-tion range, supplemented with pictures for most species encountered in the Lore Lindu National Park, LLNP, area in Central Sulawesi province. We discuss how studies like this may greatly benefit capacity-building of local scientists and tourism in the LLNP region, one of the largest rainfor-est national parks in Indonesia.

Material and methods

We collected our data in and around the LLNP, situated south of Palu, the capital of Central Sulawesi province (Fig.

1). The park covers 230,000 ha of mostly pristine tropical rainforest that partly covers mountain ranges with a maxi-mum altitude of 2356 m above sea level (mount Nokila-laki). The surroundings are dominated by agricultural land-use, mainly for cacao and coconut plantations, as well as rice cultivation. Native forest diversity is highly threat-ened by hunting activities and the land-use change of pris-tine forest into agricultural plantations.

We sampled amphibians and reptiles on 110 m transects with visual and acoustic encounter surveys (Heyer et al. 1994) and a 25-minute time constraint. more than 100 transects in six habitat types (primary and secondary rain-forest, two cacao agroforest types, rice paddies, and open areas) were checked up to six times (three times during the day and night each). Our sampling from December 2007 until October 2009 covered wet and dry seasons and an el-evational range from 400 to 2300 m above sea level (mount Nokilalaki).

In addition to our sampling, the species list including abundance, habitat use, and elevation ranges was com-

plemented with data from the literature (for references see Tabs. 1, 2). IUCN status was obtained from the IUCN RedList database (IUCN 2009, http://www.iucnredlist.org).

Nomenclature used here follows Frost (2009) for am-phibians and mcDiarmid et al. (1999) and de Lang and Vogel (2005) for snakes. For other reptiles, we used the literature sources cited in Table 2.

Results

We identified 25 amphibian species in five families and 54 reptile species in 13 families (Tab. 1). Reptiles comprised 22 snake, 28 lizard, and four turtle species (Tab. 2). While 32.0 % of all amphibian species found are not yet classified in the IUCN Red List, only four of the reptile species (the turtles) have been assessed until now. Our elevation data suggests that four of the new Limnonectes species are po-tentially high-elevation specialists and one rhacophorid is

Table 1. Amphibian species of the Lore Lindu National Park. Red List classifications follow the criteria of IUCN (IUCN 2009, http://www.iucnredlist.org): CE = Critically Endangered; E = Endangered; V = Vulnerable; NT = Near Threatened; LC = Least Concern; DD = Data Deficient; NE = not evaluated by the IUCN; Specialist [Y/N/?] = species considered a pristine-forest specialist/disturbance-tolerant species/not known; Habitat encountered = habitat where we encountered the species during the three-year survey; abbreviations used: PF = Rainforest; SF = secondary forest; AF = Cacao agroforest; CP = Cacao plantation; OA = Open area; RF = Rice paddy. Abundance was classified as C = commonly encountered; R = rare (as mentioned in the literature). Source LLNP = literature source that lists the species for Central Sulawesi Province/Lore Lindu National Park. Note that the studies by Wanger et al. (2009, 2010a) employed the same sampling methods and were conducted over the same time period as this study. Data from Amphibia Web (2009, http://amphibi-aweb.org/). Elevation = maximum elevation range in metres above sea level given in the Source El reference. If no elevation data could be found in the literature, we present the elevation at which we found the species (indicated with “F” before the figure). The symbols < and > denote occurrence below or above the elevation given, respectively. The word “lowland” is used when it was mentioned that the species would occur in the lowland without giving an elevation in metres. NA = information on the elevation range is not available.

adapted to lower elevations. The remaining amphibians oc-cur in the lowland or within a broad elevation range. None of the reptiles seem to be high-elevation specialists. For pictures of most of the encountered amphibian and lizard species see the Appendices. Photographs of most snakes of Sulawesi can be found in de Lang and Vogel (2005).

Discussion

Due to its geological past, Sulawesi’s herpetofaunal diver-sity is lower compared to the neighbouring islands such as Borneo, the moluccas or Papua (e.g., Whitten et al. 2002).

Being a global endemism hotspot, our species list supports the notion of Iskandar and Tjan (1996) that Central Su-lawesi is a very valuable area for the herpetofauna of the island. However, many areas in the region have not yet been covered by herpetological surveys – and the fact that dozens of species are awaiting formal description suggests that many more are likely to be discovered (D.T. Iskandar, pers. obs.). Our current result of few high-elevation spe-cialist amphibian and no such reptile species may just re-flect an under-sampling of mountainous habitats. A better estimate of an approximate number of elevation specialists is crucial, however, because these species will be most se-verely affected by climate change.

During this survey, we did not encounter some of the species found during previous surveys. One reason for this could be that species have declined in numbers or became locally extinct due to the rapidly progressing deforestation. This development is evident in the northeastern parts of the park (the Dongi-Dongi area), where immigrants from South Sulawesi, but also other parts of Indonesia, rapid-ly convert the forest into cacao plantations (Weber et al. 2007). As, for example, one of the study areas of the cited studies (Iskandar & Tjan 1996) focused in parts on this particular site, several species are likely to have since be-come at least locally extinct. In addition, the present study has not exhaustively sampled the area, even though most relevant habitat types were covered. We did not use pitfall traps because the effort required to maintain these setups are cost- and labour-intensive, but may not trade off well in terms of what they add to the species list. The penalty is that we are likely to have missed several secretive and fos-sorial species such as Dibamus spp., Calamaria spp., Pseu-dorabdion spp., and small skinks. The high herpetological diversity we found within this endemic hotspot is, how-ever, severely threatened by the rapid forest conversion for cacao plantation; already one million ha of Sulawesi’s land surface have been converted into these plantations to serve the global demand for cocoa (Direktorat Jenderal Perke-bunan 2008).

Recently, two ecological studies explicitly investigated the effects of land-use change on amphibians and reptiles in the Lore Lindu National Park(Wanger et al. 2009, 2010). Results indicated clearly that amphibians will be severely impacted by forest conversion, most likely due to their sen-sitivity to desiccation. For these animals, extensive pristine forest coverage is crucial for survival. many reptiles, how-ever, may benefit from agricultural habitats, as their life histories in general are more dependent on thermoregu-lation in open canopy spots (Huey et al. 2009, Wanger et al. 2010a). The sensitivity of both groups to climatic al-terations (Pounds et al. 2006, Huey et al. 2009, Wanger et al. 2009) can – to a certain extent – be made allowance for by a considerate structural management of these agri-cultural habitats. Cacao plantations with sufficient canopy cover, leaf litter thickness, and heaps of branches have a likely potential for sustaining greater herpetofaunal spe-cies richness and abundance than heavy-handedly man-aged, cleared lands. However, the main beneficiaries will certainly be common and “robust” species such as the Celebes toad (Ingerophrynus celebensis), the common sun skink (Eutropis multifasciatus), and a common but as yet undescribed skink species (Eutropis sp.).

Besides supporting conservation arguments with data (i.e., giving rough figures of how many species occur in an area), such species lists may greatly facilitate capacity-building of local researchers and field guides for ecotour-ism. For local researchers, learning the members of a local fauna by their scientific names is an important means for conducting sound scientific projects. moreover, if ecotour-ists come to remote places to see wildlife, amphibians are often the only vertebrates they get to see. It is beneficial if local guides can then name a ‘Celebes Toad’ on the basis of a brochure instead of referring to it as ‘Tete’ (i.e., the spe-cies’ name in the local language [Bahasa Toro]). Booklets for tourists will in addition provide financial support for

the national park bureau to fund the paying of often insuf-ficient salaries for local rangers.

Future research efforts should target an extensive and complete coverage of the herpetofauna of Sulawesi (D.T. Iskandar et auct., unpubl.) based on genetic and mor-phological analyses of species, many of which have so far remained undescribed. Simultaneously, explorative sur-veys in the region should continue in particular in re-mote mountainous areas where no herpetofaunistic sam-pling has so far been conducted. more ecological studies are needed to assess the effects of pesticides on amphibians and reptiles as well as biodiversity in general as forest is converted into plantation habitats (Wanger et al. 2010b). Conservation value assessments may provide guidelines of how to make secondary habitats more hospitable to biodi-versity. However, this will only work if we can take poten-tially detrimental pesticide effects into account.

Surveys were conducted un-der the research permits from Kementerian Negara Riset dan Te-knologi Republik Indonesia (RISTEK; #1899/FRP/Sm/VIII/2008; to T.C. Wanger) and Lembaga Ilmu Pengetahuan Indonesia (LIPI; #7374a/SU/KS/2007; to T.C. Wanger). Funding was pro-vided through the German Science Foundation (DFG), an En-deavour International Postgraduate Research Scholarship, and a University of Adelaide Scholarship (to T.C. Wanger).
